Yesterday in New York City, Topshop opened its first store. Along with the long lines and crowds of people, celebrities including Kate Moss, Jennifer Lopez, Blake Lively, Anna Wintour, Rosario Dawson and of course Sir Philip Green partied before and after the doors opened to celebrate the launch. Jennifer Lopez stood out in the crowd, not so much for what she wore, but for her overall appearance. I especially loved how her hair made such a difference in her style at both parties. Do you prefer Jennifer's hair slicked back and upswept or long, loose and straight with her newish fringe?
